  Hereinafter, the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the embodiments. In addition, constituent elements of the embodiments described below include those that can be easily replaced by those skilled in the art or those that are substantially the same.

  FIGS. 1-1 to 1-3, FIGS. 2-1, and 2-2 are explanatory diagrams illustrating the projector multifunction peripheral according to the first embodiment of the invention. 3 and 4 are explanatory views showing the usage state of the projector multifunction device. The projector multifunction device 100 has a main body 2 that can be moved by a caster 1, and has three functions of a projector 101, a scanner 102, and a printer 103. The printer 103 is built in the main body 2, and the projector 101 and the scanner 102 are built in the elevating unit 3.

  The elevator 3 provided with the projector 101 and the scanner 102 can be raised to a position higher than the height of the desk T as shown in FIG. In this vertical movement mechanism, two rods 5 are provided vertically on the front surface of the main body 2 (the surface on which the projection lens 4 of the projector 101 is located), and this rod 5 serves as the axis of the lifting cylinder provided on the main body 2. Moves up and down automatically or manually. The rod 5 or the like serves as a support member for the elevating unit 3.

  Since the lifting / lowering unit 3 provided with the scanner 102 and the projector 101 is provided at the upper end of the rod 5, it rises as the rod 5 moves upward. On the other hand, the height of the main body 2 itself is lower than the average height of the desk T. For this reason, while the main body 2 can be located under the desk T, the raising / lowering part 3 can be located on the desk T. In other words, the top plate of the desk T enters between the main body 2 and the elevating unit 3.

  In addition, the projection lens 4 of the projector 101 is provided on the front side of the elevating unit 3, in other words, on the side where the rod 5 serving as the support member is provided. An optical system, a light valve, and the like of the projector 101 are provided in the lift unit 3. A cover 6 of the scanner 102 is provided on the upper surface of the elevating unit 3 so as to be freely opened and closed, and a plurality of buttons 7 for operating the scanner are provided. Since the elevating unit 3 is located on the desk T, the scanner 102 and the projector 101 can be used on the desk T.

  In this way, the main body 2 is placed under the desk T, and the scanner 102 that needs to be operated and the projection lens 4 of the projector 101 that should not be hidden by objects are positioned on the desk. For example, the space on the conference room or the desk is not occupied (in particular, occupied by the printer), and the scanner 102 is easily operated.

  In addition, two casters 1 are attached to the lower part of the main body 2. As shown in FIG. 3, the main body 2 itself can be tilted by a drawer-type handle 8 and supported and carried by the caster 1. The number of casters 1 is not limited to two. For example, three or more casters 1 may be provided so that they can move without tilting. Further, one or more casters 1 may be used as driving wheels so that they can run on their own.

  FIG. 5 is an explanatory diagram showing a part of the printer structure of the projector multifunction peripheral. The projector multifunction device 100 includes a printer 103, and includes a print unit 10 having a print head and the like in a main body 2, a paper feed tray 11 that supplies paper, and a control unit 12 that controls a paper discharge direction. The paper sent from the printing unit 10 is sent to two paper discharge paths. A flap 13 for selecting a paper discharge direction is provided at the exit of the printing unit 10.

  A first paper discharge path 15 is provided below the flap 13 to reach a paper discharge tray 14 provided on the projection side of the main body 2. A second paper discharge path 17 is provided above the flap 13 to reach the paper discharge port 16 provided on the side opposite to the projection side of the main body 2. The first paper discharge path 15 and the second paper discharge path 17 are configured by combining a guide portion 18 and a paper discharge roller 19. The projection-side paper discharge tray 14 is provided with a lid 20 that can be opened and closed.

  The selection of the paper discharge direction is performed automatically or manually. When the projector multifunction device 100 is not located under the desk, the projector is discharged from the paper discharge port 16 on the side opposite to the projection direction. In other words, when the image is not located under the desk and the image is projected on the screen, if it is ejected to the projection-side ejection tray 14, it will interfere with the image projection. For this reason, it is preferable to discharge from the opposite side of the projection side. At this time, the control unit 12 drives the flap 13 to guide the paper P1 to the second paper discharge path 17 and discharge it from the paper discharge port 16.

  On the other hand, when the projector multifunction device 100 is located under the desk T (see the usage state in FIG. 4), when the paper is discharged from the paper discharge outlet 16 on the opposite side, the paper discharge outlet 16 is below the desk T. It is difficult to remove the paper. Thus, when the projector multifunction device 100 is positioned under the desk T, the paper is discharged to the paper discharge tray 14 that eventually faces the outside of the desk T. In this way, it is easy to take out the discharged paper P. At this time, the controller 12 drives the flap 13 to guide the paper P to the first paper discharge path 15 and discharge it to the paper discharge tray 14. In order to automatically select the paper discharge direction, for example, an infrared sensor 21 is provided between the elevating unit 3 and the main body 2, and when the infrared R is blocked by the top plate of the desk T, the main body 2 is selected. Is located below the desk T, and the paper discharge direction is switched from the second paper discharge path 17 to the first paper discharge path 15.

  If the infrared ray R is not blocked, the paper discharge direction remains the second paper discharge path 17 or is switched from the first paper discharge path 15. A proximity sensor may be provided on the lower surface of the elevating unit 3 or the upper surface of the main body 2, and the paper discharge path may be switched based on the output signal of the proximity sensor (not shown).

  Note that when the projector multifunction device 100 is projected close to the wall, it is difficult to remove the paper from the second paper discharge path 17, and in this case, the first paper discharge path 15 is also switched. At this time, the proximity sensor 22 is provided on the opposite side to the projection side of the main body 2 to detect the wall W, and the control unit 12 switches the paper discharge direction based on the output signal of the proximity sensor 22.

  FIG. 6 is a hardware configuration diagram of the projector multifunction peripheral. The projector MFP 100 includes a projector 101 that projects a desired image on a screen, a scanner 102 that reads a document to be projected by the projector, a printer 103 that prints a desired content, an image read by the scanner 102, and a projector 101. A hard disk 104 for storing images and the like to be projected, an optical disk drive 105 and a card reader / writer 106 for exchanging data, a ROM 107 for storing a predetermined program for control, a RAM 108 and a CPU 109 for performing predetermined processing, And an interface 110 for connection to a computer (PC) P. Slots of the optical disk drive 105 and the card reader / writer 106 are provided on the side surface of the main body 2.

  FIG. 7 is a functional block diagram showing the projector multifunction machine. The projector MFP 100 includes a control unit 150 that controls each hardware device such as the projector 101, a storage unit 151 that stores image data and the like, and a search unit 152 that searches for data stored in the storage unit 151. I have. The storage unit 151 stores image data and the like in a database (DB) 153. This database 153 organizes and stores data based on information such as customers, projects, and groups. A database management system (DBMS) 154 is provided for the database 153.

  FIGS. 8-1 to 8-4 are explanatory diagrams showing the usage state of the projector multifunction peripheral according to the present invention. When the user U is used for a conference, the projector multifunction device 100 moves from the storage location to the conference room using the casters 1 as shown in FIG. And the raising / lowering part 3 is raised (FIG. 8-2), and the main body 2 is moved under the desk T so that the said raising / lowering part 3 may be located on the desk T (FIG. 8-3). Since the elevating part 3 is supported by the two rods 5 on the front side of the main body, the top plate of the desk T enters between the main body 2 and the elevating part 3.

  As a result, the projection lens of the projector 101 is positioned in the direction opposite to the desk side, and the scanner 102 is positioned on the desk. Then, if necessary, the personal computer P is connected to the projector multifunction device 100 and projected onto the screen S (FIG. 8-4).

  In the projector multifunction device 100, the printer 103, the scanner 102, and the projector 101 perform individual functions while being connected to the personal computer P. Further, in the projector multifunction device 100, the printer 103, the scanner 102, and the projector 101 can be combined to function. For example, the user can use the projector multifunction device 100 as follows.

  When a user makes a presentation using the projector function, as a basic operation, image data is transmitted from the personal computer P, and the projector 101 projects the image. As another method, a document to be projected onto the scanner 102 (either printed matter or handwritten) is set, and this is scanned by the scanner 102. Then, the scanned image is displayed by the projector 101. That is, the projector multifunction device 100 functions like an overhead projector. The scanned image data is accumulated in the database 153 of the storage unit 151. For this reason, the slide already explained can be printed and handed over to the attendee in the middle of the meeting.

  Further, an image to be projected by the projector 101 can be read from the database 153 and projected. At this time, the user can access only data belonging to customers, projects, and groups related to him or only data belonging to his folder. The access right to the database 153 is given for each user. Note that the user reads out data directly from the storage unit 151 and projects it on the screen while referring to a liquid crystal display unit (not shown) provided in the main body 2 without connecting the personal computer P to the projector multifunction device 100. It is also possible.

  Next, the user can distribute materials to the participants in the conference room by using the printer function. The user transmits print data from the personal computer P and prints a document by the printer 103. Also, a copy function can be achieved by combination with the scanner 102. That is, a document is set on the scanner 102 and scanned, and the scanned image is printed by the printer 103. The scanned image data is accumulated in the storage unit 151. In this way, it is not necessary to distribute presentation materials in advance to the members participating in the conference, and distribution can be performed on the spot by the printer function.

  Further, the image displayed by the projector 101 can be printed by the printer 103. For example, if you want paper images projected during a meeting, you can print and distribute them on the spot. In addition, an image to be printed can be read from the storage unit 151 and printed. At this time, the user can access only the data belonging to the customer, the project and the group related to himself or only the data belonging to his folder as described above.

  Further, the contents of the database 153 can be written to an optical disk or a card-type memory and stored, or moved to another projector multifunction device 100. That is, if the stored content of one projector multifunction device 100 is moved to another projector multifunction device 100 by an optical disk or the like, the conference can be continued with the other projector multifunction device 100. Therefore, when a conference is performed using the projector multifunction device 100 at a remote location such as a separate building or a business trip destination, the conference can be continued by transferring data from the optical disc or the memory to the projector multifunction device 100.

  According to the projector multifunction device 100 described above, it is possible to hold a conference, a presentation, or the like without choosing a place by being easily moved. Further, since the projector 101, the printer 103, and the scanner 102 are all-in-one types, it is not necessary to bring in each device every time a meeting or the like is held, and a meeting or the like can be easily held. Furthermore, as described above, the projector multifunction device 100 does not perform individual functions as a simple multifunction device, but functions are combined with each other to exhibit functions suitable for a conference. . That is, the projector multifunction device 100 performs total coordination of the conference.

  FIG. 9 is an explanatory diagram showing a projector multifunction peripheral according to Embodiment 2 of the present invention. This projector multifunction device 200 is connected to a plurality of personal computers P via a LAN, and is characterized in that it functions as a database server. Since other configurations are the same as those of the projector multifunction peripheral 100 of the first embodiment, description thereof is omitted. The projector MFP 200 and the personal computer P are connected by a LAN cable, a wireless LAN, or the like. Further, the projector multifunction device 200 is connected to an Internet modem and functions as a proxy server.

  FIG. 10 is an explanatory diagram showing an example of the structure of a database. This database server includes a database 153 that stores image data projected by the projector 101, printed print data, image data scanned by the scanner 102, and the like in association with each customer, project, group, and person in charge, and this database And a database management system 154 for managing and operating 153.

  Each client P connected to the LAN has an access right to the database server. At this time, each client P can access a customer, a project, a group, and his / her folder related to the user. For example, in this projector multifunction device 200, users participating in the conference bring their personal computers P and connect to the projector multifunction device 200 via a network. This allows conference participants to access customers, projects, groups and their folders for the conference.

  The access code to the corresponding database may be automatically created and distributed by the projector multifunction device 200 for each meeting, or the chairperson may tell the participants. As a result, an unrelated person, a person who has already been removed from the member, or another third party cannot access without permission, which is particularly effective when a wireless LAN is used. In addition, the projector multifunction device 200 recognizes to which customer, project, and the like a meeting or the like belongs from the access code input by the user. As a result, the print data of the printer 103, the image data of the scanner 102, and the like are stored in the database 153 in association with the corresponding project or group.

  Each user makes a search request for desired image data in the database 153 from each client P. As a result, the image data is searched from the database 1553 of the projector multifunction device 200, and the search result is transmitted to the client P. Thereby, the client P can acquire desired image data. This image can be projected by the projector 101 in response to a request from the client P. Furthermore, the image can be printed by a request from the client P. As described above, the user can access the database 153 to acquire a necessary image, and project or print it to efficiently advance the conference.

  Further, image data to be projected from each of the plurality of clients P can be transmitted to the projector 101 of the projector multifunction device 200. In this case, an IP address is assigned to the projector multifunction device 200, and each client P is operated by a Web browser.

  FIG. 11 is an explanatory diagram illustrating an example of an operation screen.
